Как вернуть массив на основе выбранного ответа в объекте

Question

Если у меня есть объект, определенный как вопрос, как мне отобразить соответствующий массив в моем .inner HTML на основе выбора пользователя

, например

var questions = [
    {
        "question": "What area of the world are you thinking of discovering next?",
        "answer1": "Europe",
        "countryList1": "europeArray",
        "answer2": "Asia",
        "countryList2": "asiaArray",
        "answer3": "America",
        "countryList3": "americaArray",
        "answer4": "Australia",
        "countryList4": "australiaArray"        
    },
]

i Я пробовал несколько функций, но не могу отобразить правильный массив, который я создал для выбранных континентов, примеры функций, которые я создал ниже:

    var test_asia = asiaArray
    var test_america = americaArray
    var test_europe = europeArray
    var test_australia = australiaArray

    var chosenPlace = function test(questions){
        if (questions[0].answer1 == 'Europe') {
            return test_europe;
        } else if (questions[0].answer2 == 'Asia') {
            return test_asia;
        } else if (questions[0].answer3 == 'America') {
            return test_america;
        } else {
            return test_australia;
        }
    }

    result.innerHTML =
    `<h1 class="final-score">Our Recommendations:</h1>
    <div class="summary">
        <p><br></br></p>
        <p>${chosenPlace()}</p>
    </div>

Answer 1

Я сделаю что-то вроде этого:

    const questions = 
          [ { question: 'What area of the world are you thinking of discovering next?'
            , answer:
              [ { Europe   : 'europeArray'    }
              , { Asia     : 'asiaArray'      }
              , { America  : 'americaArray'   }
              , { Australia: 'australiaArray' }
            ] }
          , { question: 'Who do you intend to travel with?'
            , answer:
              [ { 'Myself'     : '6' }
              , { 'My Partner' : '3' }
              , { 'My Family'  : '1' }
              , { 'My Friends' : '6' }
            ] }
          ] 

получите ответ следующим образом:

const questions = 
      [ { question: 'What area of the world are you thinking of discovering next?'
        , answers :
          [ { Europe   : 'europeArray'    }
          , { Asia     : 'asiaArray'      }
          , { America  : 'americaArray'   }
          , { Australia: 'australiaArray' }
        ] }
      , { question: 'Who do you intend to travel with?'
        , answers :
          [ { 'Myself'     : '6' }
          , { 'My Partner' : '3' }
          , { 'My Family'  : '1' }
          , { 'My Friends' : '6' }
        ] }
      ] 


const formContainer = document.getElementById('form-container')
  ,   AnswerElm     = [...formContainer.querySelectorAll('label')]
                            .map(el=>
                              ({ op:el.querySelector('input')
                                ,sp:el.querySelector('span')
                            })) ;


console.log('AnswerElm', AnswerElm)

formContainer.onsubmit=e=>e.preventDefault();  // disable form submit

let  Q_Num = 0;
const Q_Num_max = questions.length;

function setQuestion(NoQuestion)
  {
  formContainer.reset();
  formContainer.question.value = questions[NoQuestion].question;
  AnswerElm.forEach((elm,i) =>
    {
      elm.sp.textContent = Object.keys(questions[NoQuestion].answers[i])[0]
      elm.op.value       = Object.values(questions[NoQuestion].answers[i])[0]
    })
  }
setQuestion(Q_Num)


formContainer.onclick=e=>
  {
  if (!e.target.matches('button')) return

  let elmBt = e.target.textContent

  if (elmBt == 'Next')
    {
    alert( formContainer.answer.value)
    Q_Num = ++Q_Num %Q_Num_max
    setQuestion(Q_Num)
    }
  }
